JUAN GAMARRA ELIZONDO, OF GUAYAQUIL, ECUADOR.

DRIER FOR COCOA, 80C.

SPECIFICATION forrnngpart of Letters Patent No. 514,818, dated February 13, 1894. Application led August 23, 1893. Serial No. 483,858.4 (No-model.)

To all whom it may concern,.-

`Be it known that I, JUAN GAMARRA ELI- ZONDO, of Guayaquil, in the Republic of Ecuador, South America, have invented a new and Improved Drier for Cocoa and other Grains, of which the following is a full, clear, and exact description. y My invention relates to a machine for dry- 1ng grain of any description, principally cocoa, or any material whether it be in grain form or more or less pulverized or crushed.

The object of the invention is to provide a device by means of which the grain may be dried through the medium of hot water in circulation, and to provide a means whereby further the grain while in process of drying may be kept moving through the machine, and subjected to the action of agitators at the same time.

lA further object of the invention is to provide a means whereby the hot water employed as a heating agent will be distributed to the best advantage throughout the entire machine.

The invention consists in thenovel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claim. l

Reference is to be had to the accompanying drawings forming a part o'f this specification, in which similar figures and letters of reference indicate corresponding parts in all the v1ews.

Figure l is a longitudinal vertical section taken practically on the line'1-1 .of Fig. 2. Fig. 2 is a transverse section taken essentially von the line 2-2of Fig. l. Fig. 3 is a side elevation of one of the drying chambers, a portion of one of its walls being broken away; and Fig. 4 is a plan view of the said chamber shown in Fig. 3, parts being removed.

In carrying outthe invention, a building A, is provided, which building is divided into compartments A', of greater or less extent. Each compartment, however, preferably extends from one end of the building nearly to the other.. The compartments A', have communication with like compartments B, located in what may be termed an annex B', and in the said annex the heating apparatus is located.

A drying apparatus C, is placed in each compartment A. The said drying apparatusA is of substantially box-like construction, its

body being provided with side walls 10, a bottom l1, and inclosed ends, and atop which preferably consists of a series of transverse slide-waysl2, shown best in Fig. 4, and a series of doors or gates 13, which are located in the slide-ways. When the gates or doors are in position, the box-like body of the drier is practically closed, the only openings being the exit opening 14, in the nature of a chute at the bottom of one end, a hopper 15 at the upper portion of the opposite end, and apertures 15a, adapted for the escape of surplus heat and products of evaporation, said apertures being usually produced-in the doors or gates 13. The hopper is adapted to receive the grain or other material to be dried.

In the body portion of each machine, drums 16 are held to revolve, one drum being located at or near each end, andrsaid drums carry an endless belt 17 of wire gauze or a perforated material, and in order that. the upper stretch of the belt may be held horizontally throughout its length, supporting rods 18 are provided, as shown in Fig. 3, upon which the said upper stretch rests, while the slackv of the belt can be taken up conveniently and expeditiously through the medium of tension pulleys 19, engaging with the under side of the under stretch and operated in their boxes by suitable `adjusting vscrews 20. Short shafts 21, arejournaled in theslide-ways 12 between the edges thereof, preferably at or near the center of said slide-ways, and the lower end of each shaft carries a rake 22, the teeth -whereof are curved ordinarily in direction of mounted securely upon a vertical shaft 27, lo-

cated usually at the rear end of the drier, being journaled in hangers 28,located exteriorly of the drier; and the driving shaft 27, extends from the upper compartment of the main building in which the driers are located to the bottom compartment, where it is driven by IOO any suitable or approved form of power shaft 29, or driving mechanism. One of the drums 16, is located below the hopper 15, This drum turns readily in its bearings, but the opposite dru m is mounted to turn loosely upon a shaft 2f a, said shaft being provided with a Worm wheel 30, which meshes with a worm 3l, formed upon the driving shaft 27, as shown 1n Figs. 1 and 3. This shaft 2.()a likewise has secured upon it a ratchet Wheel 32, which is engaged by a pawl 33, connected with the drum. When the ratchet and pawl are in e11- gagement the drying belt 17 is actuated, but the said belt will remain stationary when the pawl and ratchet are out of engagement, and the rakes may at that time continue to turn.

In the annex B', any approved form of hot Water heater D, is placed.A In the drawings, the heater consists of a tire pot or furnace 34 and a Water receptacle 35, located within the furnace and connected by a pipe 3G with a valved tank 37, placed in the nppermoststory of the annex and higher than the uppermost drier. Pipes 38, are made to connect with the lower Water receptacle 35, and they are carried either singly or in the shape of a coil through the various driers between the stretches of their driving belts, and are then connected with the upper tank 37, whereby a perfect circulation of hot water is obtained, and the hot water pipes at opposite sides of the structure are connected by branches 39, or a hot water heating apparatus may be employed for each tier of driers.

I desire it to be understood that hot Water is the preferred heating medium, since by its use a uniform temperature of a proper degree may be obtained and maintained.

1n operation. the material is fed into the hoppers 15; the drying belts are moved slightly by the driving mechanism, and the rakes are set in motion at the same time, and serve to p JUAN GAMARRA ELZON DO.
